Abstract
The utility model discloses a continuous titrator for the volumetric analysis of a chemical medicine; the continuous titrator comprises a burette; the upper end of the burette is provided with a side pipe with an inclined downward opening, a standard liquid storage bottle, a gas-washing bottle, a ventilating pipeline, a ventilating pipe of the gas-washing bottle, a liquid-feeding pipeline and a waste-liquid-discharging pipe switch, wherein the ventilating pipeline is connected with the gas-washing bottle and the standard liquid storage bottle, the liquid-feeding pipeline is connected with the burette and the standard liquid storage bottle and is provided with a switch, and the waste-liquid-discharging pipe switch is connected with the liquid-feeding pipeline. The continuous titrator is used for the volumetric analysis of chemical titration; the standard liquid is controlled by the switch and directly flows into the burette by the liquid storage bottle so that the inflow amount of the standard liquid can be accurately controlled; gas entering the liquid storage bottle is washed by the gas-washing bottle; and the continuous titrator eliminates the phenomenon that the standard liquid is polluted by the chemical reaction caused by the contact of alkalinity or acidity materials in air and the standard liquid. The continuous titrator can reduce operating errors, improves operating accuracy and data precision, saves operating time, improves working efficiency, saves the standard liquid and reduces the probability that chemical analysts are hurt by chemical liquid medicines.
Description
Technical field
The utility model relates to a kind of chemicals volumetry Continuous Titration device, particularly relates to a kind of buret, titration body upper end that comprises and has to oblique lower opening side pipe, titer liquid storage bottle, Drexel bottle, connection Drexel bottle and titer liquid storage bottle breather line, Drexel bottle snorkel, is connected the chemicals volumetry continuous titrator that feed liquid pipeline, feed liquid pipeline that buret and titer liquid storage bottle be equipped with switch have the waste liquid waste cock.
Technical background
The chemical capacity analytic approach is one of most important classical analysis method in the chemical analysis, it also is medicine analytical control and other chemicals check common analysis, in chemical analysis, use very extensive, be applicable to and measure constant, half major constituents, after taking some ancillary method, also can measure microcomponent sometimes.The analysis by titration accuracy is higher, measure constant, its accuracy of half major constituents is much higher than instrumental methods such as atomic absorption method, spectrophotometric method, vapor-phase chromatography, high performance liquid chromatography, although therefore instrument analytical method is more prevalent, still can not replace volumetric analysis fully.
The required instrument and equipment of volumetric analysis is simple, and buret, volumetric flask, transfer pipet, graduated cylinder etc. are arranged.The shape of the modern buret that uses is to determine in 19th century.1846, Frenchman Henry (Henry E O) invented copper piston glass drop fixed tube, has just occurred the buret of glass frosted piston subsequently soon, the appearance of promptly modern acid/tool plug buret.1855, uncommon Moore (Mohr K F) was invented the buret with scissors folder control flow velocity in the CALVER Reed, and the back develops and is modern alkali formula/uncork buret.
In the titrimetry process, each titration finishes and all need to add titer in buret, especially loaded down with trivial details for the batch measurement operation, influenced by human factor, increase stochastic error, operate miss, and titer spills easily outside buret, because titer mostly is corrosive substance or toxicant, may cause that operating personnel injure and environmental pollution; Add repeatedly in the titer process because titer exposes repeatedly, polluted by acid-base material in the air easily, cause concentration of standard solution to change, increase systematic error, the chemistry titration global error is strengthened, operating accuracy and data precision reduce.
The utility model content
The technical problems to be solved in the utility model provides a kind of chemicals volumetry continuous titrator of being convenient to operate, the utility model by the following technical solutions:
A kind of chemicals volumetry continuous titrator, comprise buret, titration body upper end have to oblique lower opening side pipe, titer liquid storage bottle, Drexel bottle, connection Drexel bottle and titer liquid storage bottle breather line, Drexel bottle snorkel, be connected buret and titer liquid storage bottle and be equipped with switch feed liquid pipeline, be connected feed liquid pipeline waste liquid waste cock, the buret upper end has to oblique lower opening side pipe, the titer liquid storage bottle has the feed flow switch, and feed liquid pipeline has the waste liquid waste cock.
Below be further improvement of these options: Drexel bottle connects snorkel, and the titer liquid storage bottle is connected with Drexel bottle by snorkel, and side pipe is connected with feed liquid pipeline by interface.
Drexel bottle seals with sealing-plug, and the titer liquid storage bottle seals with sealing-plug.
The utility model chemicals volumetry continuous titrator compared with prior art, have following characteristics: the fixing back of buret does not need to move when continuous multiple batches of mensuration, titer is directly flowed in the buret through closed conduit by liquid storage bottle by gauge tap, accurate control criterion liquid influx, too much titer can be discharged through the waste liquid waste cock, guarantee that titer adds accurately, avoids operating personnel to injure and environmental pollution; Titer is stored in the airtight liquid storage bottle, and the air that enters liquid storage bottle is cleaned by material in the Drexel bottle, stops acid and alkali substance and titer generation chemical reaction in the air, avoids titer to pollute and causes concentration change; Buret upper end feed liquid pipeline titer when oblique lower opening side pipe is avoided titration operation flows into buret.
In the real work, adopt the utility model device can reduce operate miss and systematic error, improve operating accuracy and data precision, save the running time, increase work efficiency, save titer, reduce the chemical analysis personnel and reveal the injury probability because of chemical liquid, the titrimetry effect is better in batches to be particularly useful for chemical substance.
